@@eriklapparent4662 It is actually more authentic than you would think. The Dr. 1 originally used an Oberursel rotary radial engine that was actually a French Le Rhône built under license in Germany.

Congratulations! Have been working on my own 1943 Aeronca L3-B for 5 years. Your project is amazing. Hope you upload a video flying it!! Greetings from Chile South America
It’s awesome you got your hands on an original engine and know the history of it. I am building a sopwith pup replica from the airdrome company. Going to use a verner radial
Yes, it is amazing. Orville Wright lived to see Chuck Yeager break the sound barrier, a mere 45 years after his brother made the first controlled flight in an airplane.
Though it is still amazing what they where able to do with the metallurgy and tech at the time. Honestly, those old rotary-pistons were genius for what they are.
Good to see you guys bringing history back to life. It is one thing to see a static display in a museum but it is a whole different experience to hear them breathing and screaming their proud war cries. Where I live we have the Nampa Warhawk Museum and it is a great place to not only see these old warbirds but to also learn about the people who made history.
This is unbelievable. More appropriate to be mounted to a Neuport or Sopwith, but super cool non the less. The Fokker is iconic and a perfect home for this engine. And fitting too that it came to life on November 11th. Armistice day and the day of cease fire of WW1. This just blows my mind to see. Thanks for sharing and preserving such a great piece of history.
The Oberursel engine used in the Dr. 1 (Dreidecker Einz) was a direct copy of a Le Rhône. Oberursel had a license to build Gnôme and Le Rhône engines before the war. The actual French Le Rhônes were so much better built that they were often salvaged from wrecked French airplanes and installed on Fokkers. Sopwith Camels mostly used Clerget engines. A few had Gnômes.
Congratulations John in achieving and making a childhood dream come true. It was an uphill battle that you won on11.11.2024. perseverance at its best. Enjoy the Tri..... Wana see it flying.....
I found this out only a few years ago. Amazing. It is baffling to me how any engine/aircraft designer could conceive of bolting the crankshaft stationary and having the entire engine rotate with the prop bolted to it.
Outstanding! With that entire engine a single spinning mass, flying it may prove quite a challenge. But you guys are *more than thoroughly aware of that* I am sure.
You gotta do the leg kick when pulling the prop. Gives you extra pull speed on the prop I guess. All the vintage footage I remember seeing them use a leg as they spun the prop
I just say a great big WELL DONE to everyone involved in the project. Superb commitment to a great part of aviation history. May I ask. Did Sopwith use the Le Rhone engines ? Also , how clever getting the fuel from the carb up to the cylinders ?? Great video and thanks a lot. Colin ( England )
Needing to spray fuel into the engine via the exhaust system I saw twice in my life. Civil Air Patrol an old old piper cub. Years later in an old farm tractor
Great vidio great build just one small error in the introduction the dr1 used a 100 hp Le Rhone engine, which is 80 Kilowatts, where you said it was 80 hp. Can't wait to see you fly it 🤩
@@Steve-ei2vh No error, this is an 80 hp LeRhone. The Triplane originally had a 110 hp Oberursal engine, which was basically a copy of the 110 hp LeRhone.
@adking7091 OK, my apologies I had read of the blue Max in a museum with an 80kw engine and thought droping 10hp will work. I sopose you have done the maths but dropping 30 hp on a real drag machine! I have read that most pilot's felt it was underpowered with 110 hp. I definitely will be interested to see how she performs with only 80 hp
The term 'Flying Circus' came from the fact that the German fighters of WW1 were designed and made to be disassembled moved by rail to where they were needed. Traveling circuses of the time traveled by rail as well. The civilian population seeing the planes on the rail cars associated this with the circus. The civilian population coined the phrase, 'Flying Circus'.
@@dixierebel8422 That theory has been put forth also, but the allied pilots called them the flying circus because of the bright colors, they didn't know about the rail transport.
I am curious as to why you still use Castor Oil in the engine as it has now been superseded by better performing lubricants based on mineral oil formulations.
@@joevalicenti2722 Since the fuel and oil are both sprayed into the crankcase castor oil has an advantage as a vegetable oil over a mineral oil in that it resists mixing with the fuel and reducing its lubricating qualities. It is also supposed to be advantageous in engines that use ball bearings for main bearings because of its increased surface tension over mineral oil. The Porsche guys who are running the early ball bearing engines still use castor oil, an improved non gummy version.
@@adking7091 Thank you for the detailed reply. I also would add that any other oil besides Castor Oil would not smell 'correct' for an antique engine and even though it doesn't taste great it is still better than modern oils in that sense. So in a total loss oiling system even that is an advantage!
@@tedvolz9674 They were built under license in Pennsylvania, and more were built than were used. The extra engines were sold surplus on the civilian market in the 1920s, and a few managed to survive, probably in someone's garage or shed, until they became valuable and were kept by collectors. This one ended up with a collector in the southern US, who had it for several decades I think, before deciding to pass it on to someone else, and selling it to John, the owner of the Fokker Triplane.
Love it I am Curently working on a full digital plan set of the Fokker D6 With the help of Engels Achim The goal is to make a hystoric correct set of plans And be capabole of building real Airworthy planes
Fantastic work! Now if someone can figure out how to get rid of that wretched digital stutter so that the prop (and in this case the engine) looked right when running.
@@BillThompson1955That‘s the reason the pilots wore those huge scarfs: To hold off the mildly poisonous castor oil (the other reason was the icy cold air). Nevertheless after the mission, they usually run to the toilets ..😂
I'm confused, all the parts look brand new restored or replaced. Y'all said the engine has not run since 1918 and that statement would imply its the original engine with original parts, at least in my thinking anyway. This seems to not be what I see. Anyway, regardless, its an awesome plane and great work getting it airworthy.
A technical question. Not that a game is necessarily the gold standard for accuracy, but “Ace of Aces” was otherwise fairly well-researched. In this game, rotary-engined planes enjoyed a particular performance advantage in that the mass of the rotating engine, turning counterclockwise from the point of view of the pilot, made snap turns to the right much faster. Your engine turns clockwise as the pilot sees it, which should improve snap turns left. Was the disconnect in the game mechanics, the direction your engine turns vs. original engines used in this model aircraft, or in my understanding of inertia?
This is another of the myths that have grown around the rotary engine. It is effectively a gyroscope, which reacts at 90 degrees to the applied force. In a level turn the force will react in a vertical vector. In a right turn the reaction will be in the nose down direction, this makes it easier to maintain or gain speed, which will result in a quicker turn. In a left turn the nose will try to rise which would lower the airspeed and make for a slower turn. So it becomes easier to make a tighter right turn than a left one, but the difference is not as much as the legends and myths claim.
@@rustygunner8282 Banking or rolling is along the longitudinal axis of the aircraft, which would not incur the gyroscopic force, so actual rate of roll with the ailerons making input would still be a little better to the left, but this is different from rate of turn which does incur the gyroscopic force.
The valve springs are not very strong because centrifugal force (or whatever they're calling it now) assists when the engine is running. If you pull it through by hand the valves will "flutter" off and on the seat and make that noise.
How come you guys didn't prime the engine by turning it over 6 times before contacting the egnition switch? It needs oil in the cylinder walls and fuel in the carburator.
Its my understanding Richard that doing that could lead to too much fuel and possibly ,If the engine back fires, a fire. Also you need someone on both sides to choke the air intakes. Its much easier to just prime all cylinders. they generally take right off that way
@brianwilcox3478 I thought all radial and rotory engines were the same on lubrication and priming engines. I don't know much about an 109 year old engine.
I was thinking the same thing, I've been inside a lot of vintage motorcycle engines that have been sitting since the 60s -70s and very rarely seen one that didn't have a fair amount surface rust and pitting in the cylinders, valves, and seats. I'm calling BS
@@adking7091 Do you have any experience with a rotary engine? (Personal note--my grandfather was a US Air Service cadet at Barron Field/Taliaferro #2 in 1918. He did his basic training in a JN-4, but when he began advanced training in a Sopwith Camel, the rotary engine's torque led to a ground loop, destroying the plane and leaving him too injured to fly again. May you have a much better experience!)
Amazing. This is going to be an Oshkosh star. Does it have a throttle? I thought early LeRhones were just on-off but later ones could be throttled. A friend who has time on a replica TP told me it flies sort of helicopter like, with neutral stability that requires attention all the time, but also it will point pretty much any direction you want with rudder and amazingly sharp flat turns can be made. Is that right?
@@Slithey7433 Did a little checking and the late Le Rhones had a sliding throttle plate in the air box that allowed it to be throttled back to fast idle, around 800 rpm. Having no brakes, that was too fast to sit on the ground without rolling, so the blip switch was still needed for ground operation.
@@JK-rv9tp The on-off story is mostly myth, only the 100 hp Gnome was like that. All of the other major rotary engines have a bloc tube carburetor that allows a wide range of throttling. The blip switch is only to be used at low rpm for momentary additional throttle down.
1200 RPM ignition on...and all other RPM ignition off coasting with two stroke flooding with castor oil and gas blowing out the cylinder heads. BIP BIP BIP BIP

Strictly speaking, Nov 11th is armistice day, not the end of the war. The Treaty of Versailles, which officially ended World War I, was signed on June 28, 1919.
Please be safe! A couple of times after you released the prop, you seemed to stand still, waiting to see if it would start. Please get out of this habit now. Every single time, believe that it will start and as soon as your hands come off the prop, immediately and quickly walk back. If it does not start, it is only a couple of steps forward to try again. If it does start, you will be in a safer place.
